copied!<p>You can do this using a custom <code>TypefaceSpan</code> class. It's superior to the <code>customView</code> approach indicated above because it doesn't break when using other Action Bar elements like expanding action views.</p> <p>The use of such a class would look something like this:</p> <pre><code>SpannableString s = new SpannableString("My Title"); s.setSpan(new TypefaceSpan(this, "MyTypeface.otf"), 0, s.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); // Update the action bar title with the TypefaceSpan instance ActionBar actionBar = getActionBar(); actionBar.setTitle(s); </code></pre> <p>The custom <code>TypefaceSpan</code> class is passed your Activity context and the name of a typeface in your <code>assets/fonts</code> directory. It loads the file and caches a new <code>Typeface</code> instance in memory. The complete implementation of <code>TypefaceSpan</code> is surprisingly simple:</p> <pre><code>/** * Style a {@link Spannable} with a custom {@link Typeface}. * * @author Tristan Waddington */ public class TypefaceSpan extends MetricAffectingSpan { /** An <code>LruCache</code> for previously loaded typefaces. */ private static LruCache<String, Typeface> sTypefaceCache = new LruCache<String, Typeface>(12); private Typeface mTypeface; /** * Load the {@link Typeface} and apply to a {@link Spannable}. */ public TypefaceSpan(Context context, String typefaceName) { mTypeface = sTypefaceCache.get(typefaceName); if (mTypeface == null) { mTypeface = Typeface.createFromAsset(context.getApplicationContext() .getAssets(), String.format("fonts/%s", typefaceName)); // Cache the loaded Typeface sTypefaceCache.put(typefaceName, mTypeface); } } @Override public void updateMeasureState(TextPaint p) { p.setTypeface(mTypeface); // Note: This flag is required for proper typeface rendering p.setFlags(p.getFlags() | Paint.SUBPIXEL_TEXT_FLAG); } @Override public void updateDrawState(TextPaint tp) { tp.setTypeface(mTypeface); // Note: This flag is required for proper typeface rendering tp.setFlags(tp.getFlags() | Paint.SUBPIXEL_TEXT_FLAG); } } </code></pre> <p>Simply copy the above class into your project and implement it in your activity's <code>onCreate</code> method as shown above.</p>
